Here's some more information on my system, let me know if it would be useful to know anything else.

My motherboard is a Gigabyte GA-EG45M-DS2H.

My processor is G0 stepping as someone mentioned earlier.

My memory is two 2GB sticks of Corsair XMS2 CM2X2048-6400C5.

I have an Akasa AK-P040FG7 400W power supply.

I have an APLUS CS-CURBIC case with two 180mm fans and one 120mm.
That's a pretty good case with plenty of airflow. The fact that you have a G0 will definitely help as it does run cooler and can be OC'd a little higher. The mobo seems to be decent for overclocking and the fact that it has DualBIOS is great. That has saved my butt a time or two. I would recommend upgrading your PSU though...400W isn't much in this day and age, and the mobo only supports up to 1066 DDR2 after OCing...so you might want to think about looking for a little more solid RAM.

You have the beginnings of a good OC system, but it could use some improvements.

To me those specs are ok, but the RAM "might" be an issue. See my previous post.

As to the power supply... that could go either way. I lived with my Antec HE 550 watt without any issues... though it's a "550 watt" as opposed to a 400 watt.

You could try some some OC's then go from there. Maybe try 2.6/7 and see what happens.

You WILL want to get an aftermarket CPU cooler as the 6600's get hot, especially overclocked.

Good luck.

My motherboard came with a program called Easy Tuneup which claims to help with overclocking. Would you advise trying this or just using the BIOS. What sort of settings should I be using for 2.6/2.7? I really don't have much idea of where to start.

I've just had a look at the overclock page on Everest and it is showing the CPU speed as 1600, down from 2400. Why would this be the case??

I have a Gigabyte motherboard as well, and it came with the Easy Tuneup utility. The thing about the program is, if you have SpeedStep turned on and you set Easy Tuneup to, say, 3.0Ghz, if you start doing something intensive, speedstep can bump it up over that 3Ghz mark, which could be dangerous for your processor.

I always recommend OCing through the BIOS as opposed to software overclocking. You have much more control over everything then.

It basically has to do with the processor's power settings in the BIOS. In a nutshell it's SpeedStep or EIST (Enhanced Intel Speedstep Technology) kicking in.

At low processor usage the CPU throttles back, on high loads the processor will run at full speed. However with EIST/Speedstep disabled, the processor will run at full speed, even without a load.

See this post/thread... Wrong clock speed!

Hope this helps

Oh okay that's cool.

So what settings do I need to implement to get it up to 2.6/2.7 then? And how do I check if it's stable?

I have no ideal what your BIOS settings are like. You can go here and ask these guys - GIGABYTE

Since I have a Gigabyte board that's where I went for my overclock tips

Check them out, they're pretty good. You might run into me as well.

Peace

may i ask..............and dont take this the wrong way , but why are you overclocking the cpu on that rig? The only improvement you'll see is in benchmarks such as super pi

I think your psu may be an issue if your overclocking too it seems a bit "weak"

you MUST get aftermarket cooling you cannot oc on a stock cooler
disable C1E and EIST before you start
Dont go over 1.45 volts on the cpu voltage
Dont go any higher that 1.35v on the fsb voltage
dont let your cpu run over 71 degrees in any stress test , if ity does you have to back off the clock or the voltage
Never leave any voltage settings in bios at auto
never use any utility to overclock your cpu , use yourself and your bios
3 gig is EASY on a 6600 GO , any higher and you need to start tweaking the voltage
Make sure you keep an eye on your ram speeds as you up the fsb your ram will speed up too , either unlink the ram from the cpu or manually set the dividers so it doesnt run too fast
Use 3 gig as a starting point , boot into windows and use real temp to monitor your temps and cpu/z to monitor your voltage , it will drop when under load you need to keep an eye on this (look up vdroop)
download memtest burn the iso onto a cd and boot with it , let memtest run an hour or so to make sure your ram is stable

boot into windows
run 10 passes of intel burn test on standard settings then run prime 95 for at least 2 hours , any errors you need to up the voltage to your cpu or slacken off your ram timings a little , even if prime runs for 1 hour then craps out it still means your cpu is unstable.

the 6600 is very voltage hungry at high clocks and because its 65nm it runs quite hot , to get mine stable at 3.4 i was running 1.48v in windows 1.5 in bios (i wouldnt recommend those settings)

any overclock/overvoltage is gonna reduce the life of your cpu be aware of this

good luck , and any app ive mentioned in there such as prime 95 can be easily googled

go here for any more advice

He's over here now.... GIGABYTE

And we've already told him about both the power supply and CPU cooler....twice

As to why he's overclocking that thing... Why do we overclock anything? More speed for less money

Maybe, maybe not. I saw improvements in games, not in super pi.... though I must admit I've never used super pi
